Isolators / Distributors

I. Overview

●The LU-G22 two-input two-output analog voltage/current signal isolator and distributor is suitable for connecting field two-wire transmitters, DC voltage sources, DC current sources, etc., and, after isolation and conversion, transmits the 4~20mA/1~5V analog signals they generate to the control system or other unit combination instruments.
●The isolator is powered by an independent DC power supply, with isolation between power supply, input and output. The two channels are independent of and isolated from each other.
